A suicide bombing in Baghdad has killed three people and wounded more than 20.
Police said the blast happened on March 29 near a gathering of workers in Tayaran Square, about a kilometer from a sit-in held by supporters of influential Shi'ite cleric Muqtada al-Sadr to demand political reforms.
No organization claimed the attack, but all suicide bombings carried out so far this year in the country have been claimed by Islamic State.
The Sunni militant group controls parts of northern and western Iraq.
